VALVE To all 'whom it may concern:

Be it known that I, OLAF E. OLEsoN, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented a certain new and useful Improvement in Valves, of which the following 1s a full, clear, coneiseeanfl exact description, reference being had to the accompanying drawings, "forming a part of i0 this specification.

2O struction is set out in detail, the ligure being an elevation View of valve structure, part thereof being a` longitudinal, diametrica] section. l

` The casing 1 of the valve has the coupling 25 flanges 2 and and the inlet and outlet passageways 4 and '5 respectively. The inner end o1 the passageway 5 is threaded ai S and provides the annular shoulder 7 against which engages the horizontal :flange 8 of the im annular valve seat member 9, which threads into the upper end of the outlet. The outer end of the Flangel 8 is rounded on top to form the annular bead or ridge 10 which forms a Valve seat. The member 9 has also the verN 35 tical flange 1l which extends above the plane of the l0 and Whose top face is preforably in a plane with the lower edge l2 of the inlet passageway 4c. The scat member 9 is readily secured in the outlet passageway by "l0 means of zl-'suitahle tool engaging the lugs or extensions 13.

On the valve ca sing is mounted the bonnet'. lilcomprising the cap part which is suit- Specification of Letters Patent.

groove engage in the groove 26, vertical movement of the stem then causing Vertical movement of the valve 28.r This valve 28 has the annular flange 29, extendingv downwardly to engage With a steam tight fit' in. the valve seat member 9. The valve has the outer flange 30 for engaging the valve seat 1G when the Valve is closed', and this flange at its outer edge has the protecting ridge or head 3l. Between the inner flange 29 and the outer flange 30 .is the groove 32. The face of the inner4 flange is preferably below the face of theA outer flange, and when the valve is closed, the face' of the inner flange is also below the plane of the valve seat. The depth ofthe slot 32 is also such that when the Valve is closed, there will be a chamber 33 formed by the Walls of this slot, and the upper face Aof the seat member. There Will also be an annular chamber or pocket 34 when the Valve is closed, formed lbetween the flanges ll'and S, the Valve seat l0 and the outer flange 30. ameter of the outer Valve flange is also slightly' greater than the outer diameter of the vertical flange of the seat member.

In the drawing the valve is shown closed. Upon turning of the hand Wheel, the valve `Vstem and Valve are rai-sed. The flange 30 is carried from the seat lO, but there will be no flow through the valve until the lower end of the flange 29 leaves the upper end of the flange 11. rI`he lower outer edge 35 of the flange 29 is beveled, as shown, so that the passageway through the valve will be rapidly opened Wide, the steam flowing into the inlet passageway #ll over the valve seat and into and through the outlet passage- Way During the passage of steam throu h the valve, grit, dirt kor other foreign su stances are apt to lodge on the valve seat or on the upper surface ofthe lange 1l, but when the Valve is openedLthe flow' of steam The inner dio ably securedto the top of the casing, und the across the face of the flange l1 creates more 100 yoke members 16 joining the hub at 17 at or less suction over the valve seat, and the i which is shown e bushing 1S, Awhose inner steam will carrywith it and from the Valve 'I here threaded for receiving the threaded seat any dirt or other foreign substance f. Llve stem 19. To the upper end of the Which might otherwise lodge. In fact, if stem is Secured the hand wheel 20. The stem i there are any such foreign particles in the 5U extends into the valve chemher and passes incoming steam, they will not' reach the through the guide openingl 2l and through valve seat, butWill all pass outJ through the' the cap 22'or the stuffing Thelower valve. When the Val-ve is closed and the end of the stem has the head 2l and collar lower edge of the ange 29 approaches the 25 forming the groove 2V Tne hef'i 'f Flange l of the seat member, the suction 110 effect over the valve seat is reduced and pargages :in the groove n tlcles might lodge on the Valve seat and the locking 'Ganges entre 19 2. In a vaive structure, the combination if the inclosing easinghaving an inlet passavzway and -an outlet passageway, an minnaar Yvalve seat member between the passageways having an annular flange providing a. valveing an outer Harige for engaging the valve carry any foreign particles from the valve seat and.deposit them either in thepociret 34.61 on top oA the Hangs 1l where they can do no injury, when the valve is finally seated. New, wheny the valve is again opened, the suction eect above spoken of will lift the particles from the pocket 34 and carry them through the valve and outlet passageway. The valve is centered and guided in the valve chamber' by the guide rods 36.' 1

My invention, of course, can be readily applied'to other forms of valves Afrom that herein shown without departing from the spirit or scope ofthe invention, the main feature being the relative dimensions o the various 'flanges and openings'whereby wire drawing is primarily in the greater part y prevented but just sufficient wire' drawing effect retained to cause the Avalve seat and surface to be automatically cleaned before the valve is closed.,` A valve of this oonstruction is of particular utility where it is usedas a blow-oli' valve, the bloweotf steam usually carrying a great quantity of grit and injurious foreign substances which would soon destroy the valveseat and other surfaces. As the flange 29, however, in my valve is comparatively long and does not finally open a passageway' through the valve until the outer flange of the valve has left the seat, there can be no concentration of pressure or iiow over the valve seat and consequently no injurious wire drawing effect. The wire drawingl effect, however, which is retained isi-of such low pressure as to be just sufficient to carry the foreign material. o the valve seat.

I desire to secure the 'following claims by Letters Patent 1, in a valve structure, the combination of an annular valve seat, member, a horizontal outer Bange extending from said member and having a raised surface forming the valve sezit,'a vertical flange yextending rom saidlvalve seat member above thelevel of the vulve seat, a valve having an inner annular flange for engaging with a steam tight fit in the bore of the valve seat member, an outer lange for the valve for engaging the valve seat, and a groove between the outer and ininer valve ,flanges for receiving 'the vertical flange of the valve seat member, the inner auge ci' the valve extending lower than the outer liange and also extendii'xg below 'theplene of the valve closed.v
